Les nanocristaux harmoniques de structure cristalline non-centrosymétrique possèdent des propriétés optiques non linéaires intéressantes notamment pour une utilisation comme marqueurs optiques en imagerie biomédicale.La technique de diffusion Hyper-Rayleigh habituellement utilisée pour quantifier la réponse de deuxième harmonique de nanoparticules en suspension a été étendue dans ce travail pour déterminer la susceptibilité non linéaire d’ordre 3 de différents nanomatériaux (BiFeO3, ZnO, KNbO3 et LiNbO3). D’autre part, le développement d’un montage expérimental basé sur une source accordable en longueur d’onde a permis de sonder les résonances optiques non linéaires d’ordre 2 (pour une excitation comprise entre 700 nm et 1300 nm) de ces dif...
